Issue Details

I am using NI PXI-7340 motion controller with UMI-7764 as the motion interface to control a system with 2 axes. Now I am trying control the axis one by one, both axes can move in single direction. But when I try to move them in opposite direction, the axes are still moving in their original direction. Why does this happen?
 

Solution

Open NI MAX and check your stepper output mode under Axis Configuration. If the Stepper Output Mode is configured as Step & Direction, change the mode to Clockwise/Counterclockwise.
